Entanglement recovery by reversing the effect of noise in quantum repeater
Sewon Jeong, Shrobona Bagchi, Jaehak Lee +4
We propose a method to directly recover the degree of entanglement distributed by entanglement swapping in the presence of noise. Our approach introduces a reversing operation that…
Interactions of pre- and postselected quantum particles
Gregory Reznik, Jan Dziewior, Shrobona Bagchi +1
An approach for analysis of effective interaction between pre- and postselected quantum particles is developed. It is argued that the cases of complete pre- and postselection of pa…
Concurrence speed limit and its connection with bounds in many body physics
Shrobona Bagchi
Quantum speed limit is a fundamental speed limit for the evolution of quantum states. It is the single-most important interpretation of the time energy uncertainty relation. Recent…
Non-Zero Mean Quantum Wishart Distribution Of Random Quantum States And Application
Shrobona Bagchi
Random quantum states are useful in various areas of quantum information science. Distributions of random quantum states using Gaussian distributions have been used in various scen…
A review on the questions of spin and spin quantum correlations in the relativistic regime
Shrobona Bagchi
The majority of current understanding of the quantum correlations is in the field of non-relativistic quantum mechanics. To develop quantum information and computation tasks fully,…
Stronger Quantum Speed Limit For Mixed Quantum States
Shrobona Bagchi, Dimpi Thakuria, Arun Kumar Pati
We derive a quantum speed limit for mixed quantum states using the stronger uncertainty relation for mixed quantum states and unitary evolution. We also show that this bound can be…
